How do I adjust the tension on my derailleur?

If the chain seems hesitant to shift up, increase the cable tension by turning the barrel adjuster anticlockwise.

What does the B screw do on a rear derailleur?

1 Answer. The B – screw controls the body angle of the derailleur. It pulls the pulleys away from the sprockets, so you don’t rub against them. If you set it in the largest rear cog (as you should), when you’re adequately clear, you don’t have rubbing.

Why does my rear derailleur click?

A clicking noise often comes from your chain wanting to jump up or down a gear on the rear cassette. This can typically be fixed by adjusting the tension of the cable that runs from your shifter to your rear derailleur. The clicking could be caused by a bent derailleur hanger.
